Simple fun!
Visually it looks nice, I enjoyed the shapes and the neon-like lighting, it wasn't as exaggerated. I would love to see some death animation or effect for when I kill the shapes.
Audiowise, the song is a tad repetitive and there doesn't seem to be sound effects for the shooting at all, or maybe it is too low.
I didn't see much difference it the fire rate for the minigun, it took a lot of power-ups to notice an increase in fire rate. Regarding damage, I'm not sure if I saw much difference either, considering I almost one shot every single shape, no matter the size. Every power up I'd pick the damage+fire rate or the radius for the bomb, as it seemed to kill anything in its path.
Congrats! Managed to get to round 18.
